AutoSysimages.jl - Automate user-specific system images

Package Announcements
17

To be honest, I do not see ANY effect from using AutoSysimages.

What I did (on Ubuntu):

  1. install AutoSysimages
  2. change folder of my work project
  3. run asysimg --project
  4. run include(“src/plot.jl”) from the asysimage prompt
  5. close the plot window
  6. press <ctrl>+<d>
  7. I get the message:
asysimg> 
[ Info: AutoSysimages: Copy snooped statements to: /home/ufechner/.julia/asysimg/1.8.1/23RTv7/snoop-file.jl
[ Info: There is no sysimage for this project. Do you want to build one?
 > Yes
   No

I press enter and select No for the next question (do you want to select packages).

Now it builds a system image.

If I now launch julia again and run the same include statement the time to first plot is 17s as before:

You can find and clone the example project I used here: GitHub - ufechner7/Plotting

My impression is that it creates a sysimage, but it does not use it later.

Any idea?
